Missing parts for mp7 mags

I've checked with the proshop and they've only got one part of 4 im missing from an mp7 mag.

I need the #214, #212, #213 and #209. (proshop has #212)

I see that Evike has the spring #213 but its not in stock. And I cant seem to find any other places in stock. (ASGI, redwoft, airsplat etc. checked all those). I basically googled for the parts but came up empty.
